为了解决农药污染公害问题,运城地区农业环保站从北京农业大学引进“静电超低容量喷雾”技术,在全区大面积应用示范,取得了显著成效。1 喷雾原理及应用技术“静电超低容量喷雾”是国内外尚未大面积开发使用的先进技术,其原理是:在机动喷雾器(泰山18型或东方红18型)上安装一个静电发生器,产生万伏以上的高压电场,再在喷口上安装一个超低容量喷头,使带电药液喷出时达到10～50μm 之间的微粒(肉眼看不见)。雾滴带正电荷,感应棉株带负电荷,在正负电荷作用下,药液被棉花叶片吸附于正反两面,达到杀灭害虫的效果。“静电超低容量喷雾”技术既可防治粮棉作物害虫,也可防治果树、蔬菜害虫。由
In order to solve the pesticide pollution and pollution problems, Yuncheng regional agricultural environmental protection station from Beijing Agricultural University to introduce “ultra-low electrostatic capacity spray” technology, demonstration and application of large area in the region, and achieved remarkable results. 1 Spray Principle and Application Technology “Electrostatic ultra-low volume spray” is not yet developed large-scale domestic and foreign advanced technology, the principle is: in the mobile sprayer (Mount 18 or Dongfanghong 18) to install an electrostatic generator, resulting High-voltage electric field above 10,000 volts, and then install an ultra-low capacity nozzle on the spout to make the charged liquid reach the particle size between 10 ~ 50μm (invisible to the naked eye). The droplet is positively charged, and the sensor cotton plant is negatively charged. Under positive and negative charge, the liquid medicine is adsorbed on both the front and the back of the cotton leaf to kill the pests. “Electrostatic ultra-low volume spray” technology can prevent grain and cotton crop pests, but also prevent fruit trees and vegetable pests. by
